Protein Synthesis Protein Synthesis is the process whereby DNA (deoxyribonucleic acid) codes for the production of essential proteins, such as enzymes and hormones. Proteins are long chains of molecules called amino acids. Different proteins are made by using different sequences and varying numbers of amino acids. The smallest protein consists of fifty amino acids and the largest is about three thousand amino acids long. Protein synthesis occurs on ribosomes in the cytoplasm of a cell but is controlled by DNA located in the nucleus. Protein synthesis is a two-part process that involves a second type of nucleic acid along with DNA. This second type of nucleic acid is RNA, ribonucleic acid. RNA differs from DNA in three main respects. First, the sugar units in RNA are ribose as compared to DNA's deoxyribose. Because of this difference, RNA does not bind to the nucleotide base Thymine (T), instead, RNA contains...
